  • Fiber Optics Technology - Sources and Transmitters

    Credits: 2 PDH

    PDH Course Description:

    An optical source converts electrical energy (current) into optical energy (light). Light emitted by an optical source is launched, or coupled, into an optical fiber for transmission. Fiber optic data link performance depends on the amount of optical power launched into the optical fiber. This course attempts to provide an understanding of light-generating mechanisms within the main types of optical sources used in fiber optics.

    One function of a fiber optic data link is to convert an electrical signal to an optical signal permitting the transfer of data along an optical fiber. The fiber optic device responsible for that signal conversion is a fiber optic transmitter.

    Topics:

    • Principal properties of an optical source and fiber optic transmitter
    • Optical emission properties of semiconductor light-emitting diodes (LEDs)
    • Optical emission properties of semiconductor laser diodes (LDs)
    • Typical fiber optic transmitter packages
    • Operational differences between:
    • surface-emitting LEDs (SLEDs)
    • edge-emitting LEDs (ELEDs)
    • superluminescent diodes (SLDs)
    • laser diodes
